Information Access Division

We provide evaluations, measurements and standards to advance technologies related to access to multimedia and other complex information.

In a world where technologies such as fingerprint scanners and facial recognition devices evolve on a seemingly regular basis, the Information Access Division (IAD) provides standards and measurements to accelerate this evolution. IAD not only helps complex technologies grow but also tests them to ensure they are used correctly and efficiently.

IAD supports technologies used to access potentially complex information from multimedia devices or biometric devices, such as digital video recording systems or iris scanners. Through collaborations with industry, academia, and the federal government, IAD enables the advancement of these technologies for commercial usage.
